Light-colored high-transmittance glass is provided which is made of a composition containing, as coloring components, on a weight percent basis, 0.02 to 0.06% (excluding 0.06%) total iron oxide based on Fe2O3, less than 0.024% FeO, and 0 to 0.5% cerium oxide and having a ratio of FeO based on Fe2O3 to the total iron oxide of less than 40%. The light-colored high- transmittance glass has a solar radiation transmittance of at least 87.5% and a visible light transmittance measured with the illuminant C of at least 90% when having a thickness of 3.2 mm. A glass sheet with a conductive film also is provided which includes a transparent conductive film formed on a surface of a glass sheet formed of the light-colored high-transmittance glass.
L'invention concerne du verre clair à facteur de transmission élevé, qui contient 0,02 % ou plus et moins de 0,06 %, en termes de Fe2O3 en tant que colorant, d'un total d'oxyde de fer, moins de 0,024 % de FeO et 0 à 0,5 % d'oxyde de cérium. Ledit verre présente une composition dont le rapport entre la quantité de FeO en termes de Fe2O3, et le total d'oxyde de fer est inférieur à 40 %, et comporte, lorsque son épaisseur est de 3,2 mm, un facteur de transmission du rayonnement solaire de 87,5 % ou plus et un facteur de transmission de la lumière visible provenant d'une source C, de 90 % ou plus. L'invention porte également sur une plaque de verre à couche électro-conductrice, comprenant ledit verre, et sur une couche transparente et électro-conductrice formée sur la surface de ce dernier.
